Abstract

The invention discloses a quickly cooled long-life conical rotor motor, belongs to the technical field of motors, and solves the problem that in the prior art, a conical rotor motor is prone to generating a large amount of heat, so that the conical rotor motor is difficultly quickly cooled. The quickly cooled long-life conical rotor motor comprises a shell and a rotating shaft. The rotating shaftis arranged inside the shell. A stator is connected onto the inner wall of the shell. The inner cavity of the stator is conical. A rotor is mounted on the rotating shaft, and is conical. A front end cover is mounted at the front end of the rotating shaft. The quickly cooled long-life conical rotor motor is characterized in that a fan brake wheel is connected with the rear end part of the rotatingshaft; an angle end heat conduction head is connected to the shell around the fan brake wheel; a brake cooling device is connected with the rear end of the shell; ventilation blades are mounted in thebrake cooling device; and a liquid cooling pipe is connected with the brake cooling device. The quickly cooled long-life conical rotor motor is good in cooling effect, fast to cool, stable and reliable in operation, and long in service life.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a fast-cooling long-life conical rotor motor. Background technique [0002] Conical rotor brake motor is a three-phase asynchronous motor with a tapered stator and rotor with its own brake. The inner cavity of the stator and the outer shape of the rotor are conical motors, which have the ability of self-braking when power is off, and are widely used in lifting equipment such as electric hoists and hoists. Its working principle is: after the stator is energized, a rotating magnetic field is generated, and at the same time, an axial magnetic pull is generated to move the rotor axially and compress the spring, so that the conical ring on the fan brake wheel is separated from the static brake ring, and the rotor starts to rotate. After the stator is de-energized, the axial magnetic pulling force disappears. Under the action of the spring, the rotor resets together with t...
